Next we construct a new family of 0-dimensional quantum codes. In fact the quantum codes that we are constructing in this section are extended odd-like duadic codes. Later, in Section \(\ref {section4}\) , we provide a generalization of our construction to any linear codes over \(\mathbb {F}_4\) . In spite of the known theoretical results on duadic codes and their extended codes, they are not computationally discussed much in the literature. For instance, in [1]}, the parameters of length \(n\)  duadic codes over \(\mathbb {F}_4\)  are only stated for \(n \le 41\) . Hence we take advantage of this opportunity and compute the parameters of extended duadic codes for much larger lengths (\(n \le 241\) ).
Now, we state our main result of this section.
